Improvement in steam-generators



UNITED STATES PATENT OEEIGE.

JOHN C. KLGORE, OF PHILADELPHIA, PENNSYLVANIA.

IMPROVEMENT IN STEAM-GENERATORS.

Specification forming part of Letters Patent No. 107,181, datedSeptember' 6, 1870.

To all whom t may concern:

Be it known that I, JOHN C. KILGORE, of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented a new and valuableImprovement in Steam- Boilers; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawing,making a part of this specification, and to the letters and figures ofreference marked thereon.

Figure 1 of the drawing is a side view of my invention. Fig. 2 is avertical longitudinal section ofthe same. Fig. 8 is a top view.

My invention has relation to steam-boilers 5 and consists in thesectional construction and novel arrangement of the angular pipes andthe steam and mud drums; also, in the plan adopted whereby the sectionsare secured together from the inside.

The obj ect of the invention is to avoid leakage and to prevent the mudor sediment from settling` upon the generating-surfaces.

It will be observed that the principle upon which my boiler has beenconstructed avoids level or horizontal surfaces.

The letter A of the drawing designates one of the sectional boilers. Itconsists ofthe mud-A drum B and the steam-drum C, and the angular pipesD, connecting the two drums.

The upper portion of the chamber D is bounded by parallel walls, two ofwhich are perpendicular and two oblique to the vertical plane. rlhelatter are designated by the letter e. These plane walls are connectedat the lower end of the drum with a cylindrical receptacle, E.

Hand-holes z e are formed in the ends of the cylinder E, and serve as ameans of communication between the sectional drums, and at the same timeafford access to the handvin securing the bolts which fasten thesections together.

It will be observed that the vertical walls of the drums are placed incontact with each other, the bolts a a being passed through the wallsimmediately about the edges of the handholes, and secured from theinside.

Short bolts or rivets are employed, of sufficient length to span thethickness of the two walls which are in contact.

The oblique walls ofthe chamber are inclined upward in a directionperpendicular to the direction of the pipes D.

The mud-drum is connected to the steam-l drum above by the short pipe m.The upper or steam drum, (l, is semi-cylindrical at the top, and'thencetapers downward, the converging walls h h being oblique to theperpendicular. The other two walls of the drum are vertical andparallel, and in joining the sections are placed in contact. The slopeof the inner oblique wall, h, is perpendicular to the direction of theupper branch of the angular pipes D.

Hand-holes are formed at the upper part of the steam-drum, and servesimilar purposes with those mentioned above in connection with themud-drum.

The steam-drum is connected to the muddrum by the short pipes m, and bya series of angular -shaped pipes, D, so arranged that throughout thewhole of their extent there shall be no level or horizontal surface forthe mud or sediment to collect upon. The angular pipes D consist of twobranches, respectively perpendicular in direction to the inner obliquewalls of the mud and steam drums. The two branches may be connected by acurve or bend, or by means of an angular thimble, It, as shown in thedrawing. The number of angular pipes to each section is not limited. Thelongest pipe starts from the lowest portion of the mud-drum and extendsto the upper partV of the steam-drum. Within the span of this outer pipea series of smaller angular pipes may be placed, decreasing gradually inlength until the whole of the space between the outer pipe and the drumsis filled.

In building'my boiler into brick-work, holes c n should be made tosupport the pipes D at the angles. yIn the manner above described aboiler of any size may be constructed. The sections may be kept on hand,and a small or large boiler formed by securing the proper number of themtogether.

The edges of the openings in the walls, by which the drums communicate,are secured together in the strongest possible manner, by means of shortbolts or rivets, and, from the manner of their application, they are notsubject to external violence.

What I claim as my invention, and desire to secure by Letters Patent,is-

l. The boiler herein described, composed of sections A, each sectionconsist-ing of :t downwardly-tapering steam-drum, C, mud-drum B,connectmg-tube m, and shaped or angular pipes D, substantially asspecified.

2. In combination with a steam-drum, C, :md mud-drum B, the -shapedangular or bent pipes D, having their branches inclined to thehorizontal, as specified.

3. The sectional boiler A,consisting of pipes and steam and .mud drums,provided with interior hand-l1oles .2, und secured together by shortbolts or rivets n from the inside, substantiaJlly as speciied.

In testimony that I claim the lbeve I have hereunto subscribed 1n y nameiu the presence of two witnesses.
